T BY www QM MTGZNEYS United States Patent@ Application February 2s, 19ss,`seria1 No. '118,236 n claims. ,(cl. 1sz4s) This invention relates to improvements in paint brushes and, more specifically, the invention pertains to the provision of a drip cup or receptacle for receiving paint from the -paint `brush when the same is held in an inverted position.

One of the primary objects of this invention is to provide in a paint brush means intermediate the brush bristles and handle for receiving paint from the bristles when the brush is inverted for overhead painting.

Another object of this invention is to provide in a paint brush a receptacle disposed 'intermediate the brush bristle and handle, the receptacle receiving drippings from the bristles when the brush is inverted, the receptacle having ilexible side walls which are ilexed for extruding the accumulated paint therein to return the paint to the bristles. j

A further object of this invention is to provide a paint brush of the type referred to supra, the brush having means thereon for receiving paint,firunback from the bristles when painting overhead, the means being operable to return the runback paint to the bristles with a consequent reduction in waste paint and the resulting reduction of material costs. f

A still further object of this invention is to provide a paint brush with a compartmentllled with an absorbent material, the compartment being formed of sidewalls formed of a plastic materialV being sniciently flexible `to permit the same to be turned inside out to fully expose the absorbent material thereby facilitating the removal thereof from the brush.

Still another object of this invention is to provide a paint brush of the type generally described above, together with means for insuring the connection of the side walls of the container to the paint Ibrush head to prevent the accidental and/ or inadvertent slippage thereof therefrom vduring a painting operation.

This invention contemplates, as a still further object thereof, the provision of a paint brush of the type generally described above, the paint brush being non-complex in construction and assembly, inexpensive to manufacture and durable in use.

Other and further objects and advantages of the instant invention will become more evident from a consideration of the following speciication when read in the light of the annexed drawing, in which:

Figure 1 is a perspective view of a paint brush constructed in accordance with the present invention;

Figure 2 -is an exploded perspective view of the paint brush illustrated in Figure l;

Figure 3 is a detail cross-sectional view taken substantially on the vertical plane of line 3--3 of Figure 1, looking in the direction of the arrows;

Figure 4 is a detail cross-'sectional view taken substantially on the vertical plane of line 4-4 of Figure 3, looking in the direction of the arrows; and,

on the horizontal plane of line 5-5 of Figure 3, looking in the direction of the arrows.

Referring now more specifically to the drawing, reference numeral 10 designates, in general, a paint brush constructed in accordance with the teachings of this invention. The paint brush 10 is seen to comprise an elongated handle 12 havin-g an elongated substantially rectangular base 14 integrally connected with one end thereof and extending transversely Iwith respect thereto. The base 14 receives the threaded ends 16 of a pair of elongated screws 18 provided with enlarged heads 22 having threads 24 extending inwardly from the upper ends thereof. An elongated substantially rectangular plate 26 is superposed over the headed ends 22 of the screws 18, the plate having a pair of longitudinally spaced apertures 28 extending transversely therethrough adjacent each end thereof, respectively. The apertures 28 are coaxially aligned with the screws 18.

To serve a purpose to be described below, the plate 26 is provided with a plurality of laterally and longitudinally extending struts 30.

Disposed in juxtaposition with respect to the plate 26 is a substantially hollow rectangular bristle box 32 having one end of a plurality of paint brush bristles 34 xedly secured therein in the conventional manner. The box 32 extends longitudinally of the plate 26 and is provided with an opening 36 adjacent each of its respective ends through which extend screws 38 for engagement with the internal threads 24 of the head 22 formed in the screw 18.

Reference numeral 40 designates a substantially rectangular casing formed of rubber or of any other suitable ilexible plastic material, the casing 40 having a pair of opposed open ends. One end of the casing 40 is bonded or otherwise secured to a continuous peripheral ange 42 formed of an elastic material such as, for example, rubber,` the a'nge 42 being provided at its outer end with an integral inwardlyrextendin-g lip 43, which serves a function to be described below.

As is 'clearly seen in Figuresl, 3, 4 and 5,the outer ends `of the strutsg30 are integrally formedorptherwise rigidly secured' to thexinnersidelof a continuous substantially rectangular ange 44. In accordance with this invention, the lip 43 is hooked over the outer end of the ilange 44 to prevent the accidental or inadvertent displacement therefrom of the resilient ange 42. The other open end of the casing 40 is secured to the base 14 as by nails or tacks 45.

As is seen in the gures, the struts 30 hold the ange 44 in spaced relation relative to the plate 26 to form passages 48 therebetween.

The handle 14, casing 40, plate 26 and flange 44 define a substantially hollow compartment 46 adapted to receive paint absorbent material 49, which may be formed of sponge rubber or of any other suitable material.

The brush 10 is manually operated in the conventional manner, the members making up the compartment 46 possessing sufcient rigidity to prevent the turning of the bristles 34 relative to the handle 12. However, the paramount advantage of the brush of the instant invention over conventional paint brushes becomes most evident when engaged in painting overhead. Under such conditions, the brush 10 is inverted and the bristles 34 thereof may be saturated to their maximum paint retaining capacity and, as is now obvious, any paint runback or drip ytowards the handle 12 due to gravity will pass from the bristles 34 through the passages 48 and into the compartment 46 where the same is absorbed by the absorbent material 49.

At any time after paint begins to accumulate within the casing 40 the operator may invert the brush 10 from the positions thereof illustrated in Figures 1 through 4, inclusive, and through the simple expedient of squeezing the casing 40 the paint accumulated in the compartment 46 and in the absorbent material 49, will be extruded through the passages 48 back upon the bristles 34.

The sponge rubber or other absorbent material 49, in addition to absorbing paint accumulated within the compartment 46 during overhead painting, serves still another function.' For example, when the brush user changes from overhead painting `to general painting, that is, for example, to wall painting, the paint accumulated within the compartment and absorbed by the material 49 would have a tendency to leak back through the openings or passages 48 which would cause undesirable drip and paint wastage. The absorbent material prevents this from occurring.

Through the provision of a ilexible casing such as designated at 40 and the flexible ange 42, the user of the paint brush may detach the lip and lange 42, 43 from the llange 44 and turn the casing inside out. The absorbent material 49 may now be removed and the inner side of the casing cleanedvin the event the user contemplates a change in the color of the paint being used. Additionally, and by virtue of this brush construction, the brush bristles 34 may be readily replaced through the simple expedient of removing the screws 38 and replacing the bristle unit.

Having described `and illustrated one embodiment of this invention in detail, it is to be understood that the same is otfered merely by way of example, and that this invention is to be limited only by the scope of the appended claims.
